GOLD ENRICHMENT MECHANISM IN MID-OCEAN RIDGE HYDROTHERMAL SYSTEMS: AN EXAMPLE FROM THE LONGQI HYDROTHERMAL FIELD ON THE ULTRASLOW-SPREADING SOUTHWEST INDIAN RIDGE

Kean Chen, Huichao Zhang, Nigel J. Cook, Chunhui Tao, Fang An, Jin Liang, Weifang Yang
Journal: Economic Geology
Published: 01 September 2024
Economic Geology (2024) 119 (6): 1413–1431.
DOI: https://doi.org/10.5382/econgeo.5095
... the distribution of gold in sulfides from hydrothermal fields hosted by ultramafic rocks. In contrast, the gold enrichment mechanisms in sulfides from hydrothermal fields hosted by mafic rocks in ultraslow-spreading ridge environments are less well constrained. The basalt-hosted Longqi hydrothermal field, located...

Magmatism at oceanic core complexes on the ultraslow Southwest Indian Ridge: Insights from near-seafloor magnetics

Fei Zhou, Jérôme Dyment, Chunhui Tao, Tao Wu
Journal: Geology
Published: 24 March 2022
Geology (2022) 50 (6): 726–730.
DOI: https://doi.org/10.1130/G49771.1
.... The termination separates volcanic terrains to the north and the detachment surface where serpentinite samples were dredged. Farther south, a chaotic volcanic area, where dredges recovered basalt, hosts a hydrothermal field with large sulfide deposits ( Tao et al., 2014 ; Liao et al., 2018 ). Longqi OCC...

... of hydrothermal plumes on the SWIR and the discovery of the Longqi field, the first active hydrothermal field found on an ultraslow-spreading ridge ( Tao et al. 2012 , Figure 1 ). Subsequently, many more hydrothermal fields have been discovered on the ridge ( Tao et al. 2014 ; Chen et al. 2018 ). As noted...
